Dreizehn Travertinproben von den Lokalitäten Tata, Vértesszöllös, Dunaalmás und Buda werden mit Hilfe zweier neuerer Absolutdatierungsverfahren untersucht, der Th-230/U-234- und der ESR-Methode. Für acht der untersuchten Proben ergibt sich eine

Durch die ESR-Altersbestimmungsmethode (Elektronenspin Resonanz) sowie die 230Th/234U-Datierung fossiler Muscheln bei Tarquinia (Latium) konnte die stratigraphische Einordnung tektonisch verstellter thyrrenzeitlicher mariner Terrassen geklärt werden

In 1982, four homogenized calcite samples of differing ages and origin and one fossil bone sample were investigated by 16 laboratories engaged in ESR dating. The goal of phase II of this project was to determine the precision of ED evaluation that ca

Dense speleothem samples are considered as closed systems and are, therefore, possibilities for any dating method. Four dating methods (14C, U/Th, paleomagnetism, and electron spin resonance = ESR) were used for samples up to 1,000,000 yr old and tak

The age of the hominid cranium discovered in 1960 in a limestone cave near Petralona (Greece) is a continuing cause of controversy. The age of the skull, which was apparently encrusted by brown calcite soon after the death of the individual concerned

Absolute age determinations of calcite formations in caves as e.g. stalagmites are often of archaeological interest, especially if relics of prehistoric life are chronologically interrelated to such "speleothems". Because the growth speed of stalagmi

The study of coastal deformation and sea-level history calls for radiometric ages on shorelines older than the past 20,000 yr, the period for which reliable 14C ages can be obtained. Uranium-series disequilibrium methods have yielded the requisite ag
